225/60 R16 vs 235/65 R16
235/65 R16 is a wider variation of 225/60 R16 on the same 16-inch rim, adding 10 mm of tread footprint. This tire combination noticeably changes overall diameter compared to OEM. More sidewall typically improves comfort and curb protection, especially on city streets.
Speedometer error is large enough that recalibration is effectively required for accurate readings. A diameter change beyond 5% is aggressive enough to influence ABS, traction control and gearing; treat it as a serious modification.
TakeTreat as a serious modification — verify clearance, recalibrate the speedometer and reassess load capacity.
Quick math: 235/65 R16 is 35.5 mm taller than 225/60 R16, shifting the speedometer by +5.25%.

Speedometer impact
At a true 100 km/h, your dashboard will read 105.2 km/h after switching to 235/65 R16 — a +5.25% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +17.8 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
